The displacement of spectral lines toward longer wavelengths (the red end of the spectrum) in radiation from distant galaxies and celestial objects. This is interpreted as a Doppler shift that is proportional to the velocity of recession and thus to distance.

The speed of the particle is proportional to = √t

Work = the change in kinetic energy = 1/2 mv2

If work is proportional to time

W = t

1/2 mv2 = t

v2 = t

v (speed) = √t

Speed is the time rate at which an object is shifting along a path, even as speed is the fee and route of an item's movement. Positioned every other manner, speed is a scalar value, even as pace is a vector.

Velocity (or price, r) is a scalar quantity that measures the gap traveled (d) over the alternate in time (Δt), represented via the equation r = d/Δt.

The Italian physicist Galileo Galilei is credited with being the first to measure speed by considering the gap blanketed and the time it takes. Galileo described pace as the gap covered in line with unit of time.

A vibrating pendulum makes 20 complete vibrations in 12.2 seconds. Determine the vibrational period of the pendulum, along with
Hitman42 [59]

Answer:

And the same can be said of a pendulum vibrating about a fixed position or of a guitar ... along the time axis, it is possible to determine the time for one complete cycle. ... It takes 2.3 seconds to complete the first full cycle of vibration. ... Since the standard metric unit of time is the second, frequency has units of cycles/second.
